WVhen the hereinafter fully described, and particularly screw at is turned relatively to the nut 5, it pointed outinthe claims, reference being had is obvious that either the screw must feed to the accompanying drawings, forming part downward or the nut must feed upward.

By regulating the tension on spring 11, which may be done by adjusting the threaded follower in the yoke 13 and fixing the follower to its adjustment by the set-screw 16, the degree of pressure exerted by the plunger 3 upon the adhesive material before the plunger will rise to disconnect the clutch may be regulated at will. This adjustment, together with a suitable selection of turning connections which drive the wheel 6, will enable the operator to control the expulsion of the adhesive material from the reservoir to a nicety.

The worm-wheel 6 may be turned by the worm 17, rotated through a suitable gearing from the cigarette-machine, or said wheel 6 may be constructed to be driven byany other suitable means.

In order to permit the convenient removal of the plunger from the paste-cup without turning back the feed-screw in its nut, which would take considerable time, the nut 5 is formed in two parts 5 and 5 ,,as shown more clearly in Fig. 4, and a collar has pins 21 projecting vertically into eccentric slots 22, formed in the parts of said nut 5, so that when the nut is rotated slightly by the lever 23 the parts of the nut will be forced away from the screw and said screwis free to move longitudinally. The pins 21 are long enough "to retain their control over the parts of the nut 5 even though the latter be raised, as hereinbefore referred' to, to disengage the clutch. An important novel advantage accrues from this in that when the nut has been fed upward in opposition to spring 11, by reason of abnormal obstruction to the downward feed of the plunger 3 and the machine has been stopped with the parts in this condition, the nut may be permitted to fall again to bring the parts of the clutch 7 into engagement by simply spreading the nut 5 to disengage it from the screw.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In combination with a paste-reservoir having an expelling-plunger, a feed-screw advancing said plunger, an axially-movable, spring-pressed nut advancing the screw, turning connections through which relative rotation between the screw and nut is effected, a

clutch interposed in said turning connections, and displacing connection between the axially-movable nut and the movable member of the clutch, acting upon the latter in the direction of releasing movement.

2. In combination with a paste-reservoir having an expelling-plunger, a rotatable feedscrew, advancing said plunger, a non-rotating,axially-movab1e nut advancing the screw, turning connections through which rotation is imparted to the screw, a clutch interposed in said turning connections, having one of its members movable into and out of engagement with the other member of the clutch, a spring pressing the members of the clutch together, and displacing connection between the axially-movable nut and the movable member of the clutch, acting upon the latter in the di rection to release it.

3. In combination with a paste-reservoir having an expelling-plunger and a feed-screw advancing said plunger; means for rotating said -feed-screw, including a clutch having its members coaxial with the feed-screw, one member rotating about the screw and its other member splined to but axially movable on the screw, means for yieldingly pressing the mem* bers of the clutch together, and an axiallymovable, non-rotating feed-nut held in the direction of feeding by said movable clutch member and movable upward under abnormal pressure beneath the plunger and having dis placing connection with the movable member of said clutch.

4. In a pasting device, employing a reser} voir, an expelling -screw, and a screw fed plunger; means for advancing the screw com prising an axially-movable non-rotating nut on said screw, a driving gear-wheel concentric with said screw, an axially-movable clutch member having clutch connection with the gear-wheel and splined connection with the screw, a spring pressing the clutch member into engagement with the gear-wheel,- and dis placing connection between the nut and the movable member of the clutch, whereby the nut disconnects the clutch by its movement.

5. As a means for advancing the feed-screw of a pasting device for cigarette-machines,- the combination of a longitudinally-movable, non-rotating nut 5, through which the screw advances, a coaxial, longitudinally-movable turning head 8 having splined connection with the feed-screw, a spring pressing downward upon said turning head, a driving-wheel 6 rotating about the screw, said turning head and driving-wheel being formed with engaging clutch-faces, and a displacing connection between the longitudinally-movable nut and said turning head,whereby thelatter is moved in opposition to its springby the longitudinal movement of the nut.

6. In a pasting device for cigarette-marid chines, the combination of the reservoir, the

tudinally-movable nut, the turning wheel,

ing wheel and sustaining the upper end of the bushing working through the turning the spring.
